The early Caenorhabditis elegans embryo contains abundant transcripts for two α-and two β-tubulins raising the question of whether each isoform performs specialized functions or simply contributes to total tubulin levels. Our identification of two recessive, complementing alleles of a β-tubulin that disrupt nuclear-centrosome centration and rotation in the early embryo originally suggested that...

BACKGROUND Although endobronchial ultrasound (EBUS)-guided transbronchial biopsy (TBB) has been shown to increase the diagnostic yield over conventional bronchoscopic techniques, an important issue regarding the optimal number of biopsy specimens required has not been thoroughly investigated. OBJECTIVES We sought to examine whether the number of biopsy specimens taken was associated with the ...

STUDY OBJECTIVES We evaluated the feasibility, safety, and efficacy of transbronchial biopsy (TBB) using endobronchial ultrasonography with a guide sheath (EBUS-GS) and virtual bronchoscopy (VB) navigation for small peripheral pulmonary lesions < or = 30 mm in diameter. DESIGN Pilot study. SETTING A national university hospital. PATIENTS We performed TBB using EBUS-GS with VB navigation f...

The most efficient parallel execution of dense liner algebra algorithms is to build and evaluate the task graph constrained only by the data dependencies between the tasks. Both Intel C++ Concurrent Collections (CnC) and Threading Building Blocks (TBB) libraries allow such task-based parallel programming. In this paper, we first analyze all the three types of data dependencies in the tiled in-p...

The purposes of this study were twofold, namely to evaluate: (1) the effect of hybridization on microtensile bond strength (microTBS) to dentin, and (2) the ultrastructure of the dentin-adhesive interface with 4-META/MMA-TBB resin after acid-base challenge. Dentin surfaces, which received no treatment (NT), 65% phosphoric acid (PA), or 10% citric acid-3% ferric chloride (10-3), were bonded with...

Intel Threading Building Blocks (TBB) is an ideal environment for implementation of the parallel dynamic programming design pattern. The task-based parallelism of TBB readily lends itself to the realization of the participants and participant collaboration of this design pattern. We propose the parallel dp algorithm template, an implementation of the parallel dynamic programming design pattern ...

Intel’s Threading Building Blocks (TBB) provide a high-level abstraction for expressing parallelism in applications without writing explicitly multithreaded code. However, TBB is only available for shared-memory, homogeneous multicore processors. Codeplay’s Offload C++ provides a single-source, POSIX threads-like approach to programming heterogeneous multicore devices where cores are equipped w...

Abscess formation in lung cancer after transbronchial biopsy (TBB) is a rare complication with no standard consensus on a coping strategy or prophylaxis. We describe an instructive case of lung cancer which developed into an abscess after TBB. An 80-year-old man with poorly controlled diabetes mellitus underwent TBB for diagnosing a mass lesion in the left upper lobe. The TBB specimen confirmed...

The adequacy of intestinal perfusion during shock and resuscitation might be estimated from intestinal tissue acid-base balance. We examined this idea from the perspective of conventional blood acid-base physicochemistry. As the O(2) supply diminishes with failing blood flow, tissue acid-base changes are first "respiratory, " with CO(2) coming from combustion of fuel and stagnating in the decre...
